Finding Slope on a Graph

The video tutorial explains how to find the slope of a line on a graph by identifying lattice points and calculating the vertical and horizontal changes. It covers simplifying slopes and discusses the unique cases of horizontal and vertical lines, where slopes are zero and undefined, respectively.

What is the first step in finding the slope on a graph?

• Identifying the y-intercept

• Identifying lattice points

• Drawing a straight line

• Calculating the distance between points

What do lattice points represent on a graph?

• The intersection of two lines

• The highest point on a graph

• The corners of grid squares

• The midpoint of a line

How do you determine the change in y when calculating slope?

• By counting the horizontal spaces

• By counting the vertical spaces

• By identifying the x-intercept

• By measuring the distance between points

What is the simplified form of the slope if the change in y is 4 and the change in x is 6?

• 1/2

• 3/4

• 4/6

• 2/3

If you move up 6 points and left 8 points, what is the slope?

• -3/4

• 4/3

• 3/4

• -4/3

What is the slope of a horizontal line?

• Undefined

• Zero

• Positive

• Negative

Why is the slope of a horizontal line zero?

• Because there is no vertical movement

• Because there is no horizontal movement

• Because it intersects the x-axis

• Because it intersects the y-axis

If a line has no change in y, what is its slope?

• Negative

• Zero

• Positive

• Undefined

What is the slope of a vertical line?

• Positive

• Undefined

• Negative

• Zero

Why is the slope of a vertical line undefined?

• Because there is no vertical movement

• Because there is no horizontal movement

• Because it intersects the x-axis

• Because it intersects the y-axis
